Even if it is legal to take a human life to protect property, I don't think it is justifed on moral grounds...Not to mention the civil lawsuit which could drain you of everything you have left that the criminal did not have the opportunity steal...It just ain't worth it to me...However,if I determine my life or other innocent bystander is in danger or with severe physical harm...I'll stop the criminal with deadly force if necessary and worry about civil lawsuits latter.
Not that I disagree with you, but..
Is it possible that "Its not worth it to you" because you haven't been repeatedly stolen from?
Or you haven't had your last $20.00 stolen from you, so you couldn't eat for the rest of the week?
If it is ok to steal, as long as its done in a non violent manner, then why not make it legal?
Is it possible that you actually have a moral responsibility to protect what belongs to your family, even if it means using "deadly force".?
